Experimenting with the new sublimation printer we have at work, I made an extra-large ketchup packet pillow, as well as this mug themed from the Namco Quick and Crash arcade game. The sublimation printer uses a special kind of infuse-able ink, which bonds to polyester fabrics as well as anything that has been treated with a sublimation ready coating, like the mug.
